4.3.4. Registries which capture special populations

In assessing both safety and
effectiveness, special populations can be identified based on age (e.g.,
paediatric or elderly), pregnancy status, renal or hepatic function, race, or
genetic differences. Some registries are focused on these particular
populations. Examples of these are the birth registries in Nordic countries.
